Abstract
The utility model discloses a double-layer filtering smoke exhaust ventilator comprising an air inlet channel arranged in a shell, wherein a rectification plate is arranged at the inlet of the air inlet channel, a filtering net is arranged in the air inlet channel, and gaps are arranged between the peripheral edges of the rectification plate and the inner wall of the air inlet channel. The double-layer filtering smoke exhaust ventilator has the advantages that oil foulant content contained in the smoke gas exhausted outside is reduced as the sucked oil smoke is collided twice, and a majority of oil foulant is filtered, and the environment-friendly use effect is achieved.
Description
Technical field
The utility model relates to a kind of range hood.
Background technology
Be provided with screen pack in the air intake passage of common range hood, the oil smoke of suction bumps with it through screen pack the time, and speed slows down, and from air-flow, removes.In order to improve the oil smoke absorbing effect, the way that adopts usually is to strengthen power of fan, promotes suction.But oil smoke too high levels in the gas that can cause like this discharging is polluted external environment condition.
Summary of the invention
The purpose of the utility model is to provide a kind of double medium filtration range hood that can reduce oil smoke content in the air-flow.
The technical solution of the utility model is: a kind of double medium filtration range hood; Comprise the air intake passage that is arranged in the housing; Be provided with cowling panel at said air intake passage inlet, in said air intake passage, be provided with screen pack, have the gap between edge, cowling panel surrounding and the said air intake passage inwall.
Be provided with cowling panel and screen pack in the air intake passage, realize two heavy filtrations, when the oil smoke elder generation process cowling panel of suction and the gap of air intake passage; The deceleration that bumps, the part oil droplet is filtered, after further filtering through screen pack again; Oil smoke content is lower in the gas of discharging, and has reached the effect of environmental protection.
Said cowling panel is movably arranged in the said air intake passage.Conveniently take off cleaning.
Said cowling panel is two that are provided with at interval.Increase the chance of oil smoke collision, improve filter effect.
The utility model has the advantages that: make the oil smoke of suction carry out twice collision, most greasy dirt is filtered, reduce greasy dirt amount contained in the external discharged flue gas, reach the result of use of environmental protection.

The specific embodiment
Embodiment 1:
Consult Fig. 1; A kind of double medium filtration range hood comprises the air intake passage 2 that is arranged in the housing 1, is provided with two cowling panels 3 that are provided with at interval in air intake passage 2 porch; In air intake passage 2, also be provided with screen pack 5, have gap 4 between the inwall of cowling panel edge, 3 surrounding and air intake passage 2.
The soot gas that is inhaled into will be walked around two cowling panels 3 earlier; 4 get in the air intake passage 2 from the gap, and in this process, oil smoke liquid can bump with cowling panel; Speed reduces; Be filtered out, the soot gas that gets in the air intake passage 2 can further bump with screen pack 5, most greasy dirt is filtered discharge.The separating degree of greasy dirt can reach more than 87% more environmental protection in the gas of discharging at last.
Embodiment 2:
Consult Fig. 2; A kind of double medium filtration range hood comprises the air intake passage 2 that is arranged in the housing 1, is provided with a cowling panel 3 in air intake passage 2 porch; In air intake passage 2, also be provided with screen pack 5, have gap 4 between the inwall of cowling panel edge, 3 surrounding and air intake passage 2.Other technical characterictic is identical with embodiment 1, does not repeat them here.
Above-listed detailed description is to the specifying of the utility model possible embodiments, and this embodiment is not the claim in order to restriction the utility model, does not allly break away from the equivalence that the utility model does and implements or change, all should be contained in the claim of this case.
Claims (3)
1. double medium filtration range hood; Comprise the air intake passage that is arranged in the housing; It is characterized in that: be provided with cowling panel at said air intake passage inlet, in said air intake passage, be provided with screen pack, have the gap between edge, cowling panel surrounding and the said air intake passage inwall.
2. double medium filtration range hood according to claim 1 is characterized in that: said cowling panel is movably arranged in the said air intake passage.
